LUBFIICA''OR.y

SPECIFICATION forming part of Letters Patent No. 266,058, dated October 17, 1882.

Application tiled April E26, 1 582.

To all whom it may concern:

Be it known that I, CHARLES W. SHER- BURNE, of Somerville, in the county ot' Middlesex and State otMassachusetts, haveinvented certain new and useful Improvements in Lubricaiors, oi' which the following is at'ull, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specilication, in explaining its nature, in which- Figure l represents in vertical section and elevation my invention. Fig. 2 is a plan view below the line a; x ot' Fifi. l. Fig. 3 is a horizontal section on the line x of Fig. 1.

The invention is adapted especially for use on locomotives, although ofcourse it is notconfined to that use, for it can be used in connection with a stationary or marine engine, it' desired.

The object ot the invention is to provide a double lubricator, one portion ot' -which is worked when the principal engine is at rest for the purpose ot lubricating some smaller engine, pump, or other device which may continue in operation. Take, t'orinstance, the case ot' alocomotive. The lubricator ordinarilyused upon thelocomotive hasitscondensing-cham ber supplied with 'steam from the dry-pipe. Consequently upon the stopping ot' the locomotive the steam is shut oit' and the lubricator ceases to act; and this construction is well enough when the lubricator is simply used for lubricating the cylinders ot' the engine; but as the engine of the Vestinghouse air-brake is geuerally kept at work while the locomotive is at rest, its cylinders, ofcourse, cannot receive lubrication while the locomotive is at rest if the steam-supply is shut ofi' from the condensingchamber. Yet it is very desirable that the cylinders be lubricated while the locomotive is at rest, but at the same time it is not desirable that the cylinders ot' the locomotive be lubricated. To overcome these difficulties I provide mylubricator with two oil-chambers, one ot which is connected with acondensing-chamber receiving steam from the dry-pipe, and the other ot which is connected with a condensingchamber receiving steam from the steam-dome. Of course these oil-chambers may be entirely separated from each other and be distinct ves-- (No model.)

the construction herein indicated, which consists in dividing the ordinary oil-chamber by a partition into two chambers, one ot' which shall contain oil for lubricating the cylinders ofthe locomotive and the other of which shall contain oil for lubricating the cylinders ofthe airpump, or for any other purpose.

Referring to the drawings, A represents the receptacle or cup for containing the oil. It is divided by the partition a into the chambers a a2. The chamber c is connected with the condensing-chamber B by means of the pipes a3 a4, and the con den sing-cham ber B is connected with the dry-pipe ofthe boiler by means ofthe pipe b. The chamber A is connected with a sight-feed, so called, being a visible feed of drops of oil conveyed through water, such as is described in the Gates Let-ters Patent N o. 138,243, by means ofthe passage a5 in the pipe a6. This passage opens into the passage in the `benttube aT within the transparent chamber a8,

whereby the oil is fed to uearits bottom. From this chamber a the oil passes up through water or other transparent medium to the pipe a9, by which it is conveyed to the dry-pipe.. The chamber c2 has the pipe c,which extends very nearly to the top thereof` and is open at its top, and is connected at the bottom with the passage c' in the pipe or connecting-piece c2. The passage c is connected with another drop-feed, substantially like that already described, and is represented by c1", the bent tube inside byct. From the drop-feed the oil, by suitable piping, is conveyed to the places where needed. The oil-chamber a2 is connected with the condensing-chamber C by means ofthe passage c3 in the pipe c2 and the pipe c4, which opens into said passage c3; and the condensing-chamber C is connected with the steam-dome by means of the connecting-pipe c5. The pipe or connecting-piece c2 also has the passage c controlled by a valve, c7, for removing or draining the water from the Aoil-chamber when necessary. The lubricant has, of course, suitable controlling-valves forclosing and opening the passage between the condensers and the oil-chambers, between the sources of steam-supply and the 'condensers, and hetweenjhe sight-feeds and the sight-feed chambers with water, and thev oil-chamber a has means for draining it.

lOO

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States- 1. In a lnbricator, the combination of the oil-chan'ibers a (L2, two sight-feed devices, two condensers, one ot which ,is connected directly with thelloiler or steam-dome, and connecting piping, as specified, all substantially as and for the purposes described.

2. A sight or visible feed lubricator having` one oil-supply cup separated internally into two chambers and connected with condensingchambers, and adapted to receiS'c steam from two distinct sources and to lnbzicate two independent machines, all substantiallyv as and for the purposes described.
